A waterproof brake cylinder

Abstract

The invention discloses a waterproof brake cylinder, which comprises a brake cylinder body and a front cover. The front cover is provided with a waterproof and dustproof cover, and the waterproof and dustproof cover consists of a The dust cover and the dust filter felt frame and the dust filter felt pad arranged in the dust cover, the dust filter felt frame is connected with the dust cover, and the dust filter felt pad is fixed on the dust filter felt frame, at the edge of the dust cover There is a skirt extending outward along its axial direction. The present invention arranges a sealing structure at the position where the existing brake cylinder is easy to enter water, effectively preventing the rainwater from being sucked into the cylinder by the negative pressure formed in the brake cylinder when the brake cylinder is relieved, so as to play a waterproof role and improve braking efficiency. The service life of the cylinder ensures driving safety.

Description

technical field [0001] The invention belongs to the technical field of vehicle brake cylinders, in particular to a waterproof brake cylinder. Background technique [0002] The brake cylinder of railway vehicles is generally installed at the bottom of the vehicle, and the body of the vehicle will block rainwater from entering the cylinder, such as gondola cars and boxcars. However, for some models, such as flat cars, tank cars, cement trucks, etc., the car body does not completely block the brake cylinder, and rainwater can easily pour into the brake cylinder and enter the brake cylinder. [0003] Such as figure 1 As shown, the brake cylinders of existing railway wagon vehicles have only dustproof function and no waterproof function. figure 1 A, B, and C in the center flow into the brake cylinder, especially when the brake cylinder is relieved, negative pressure will appear on the right side of the piston of the brake cylinder, and rainwater is more likely to be drawn into ...

AI Technical Summary

Problems solved by technology

However, for some models, such as flat cars, tank cars, cement trucks, etc., the car body does not completely block the brake cylinder, and rainwater can easily pour into the brake cylinder and enter the brake cylinder.

[0003] like figure 1 As shown, the brake cylinders of existing railway wagon vehicles have only dustproof function and no waterproof function. figure 1 A, B, and C in the center flow into the brake cylinder, especially when the brake cylinder is relieved, negative pressure will appear on the right side of the piston of the brake cylinder, and rainwater is more likely to be drawn into the cylinder, resulting in braking Pollution and rust inside the cylinder will greatly reduce the service life of the brake cylinder and affect driving safety
